Abstract

Described herein is the isolation and identification of a number of sulfur oxidizing plant growth promoting rhizobacteria: RAY12, identified as Achromobacter piechaudii; RAY28, identified as Agrobacterium turnefaciens, RAY132, identified as Stenotrophomonas maltophilia; and RAY209, identified as Delftia acidovorans. The PGPR act to oxidize elemental sulfur which in turn provides sulfate for the plants. As a result of this arrangement, plants are able to grow more efficiently and effectively and have enhanced growth characteristics, for example, but by no means limited to, increased vigor, early emergence, increased emergence rate, increased biomass, increased plant leaf area, higher crop yield, increased pod number, increased pod weight, increased root biomass, increased seed weight, increased macro- and micro-nutrient uptake and the like. The sulfur-oxidizing PGPR may be applied to seeds, seed pieces, carrier materials, roots and planting soil.

Description

PRIOR APPLICATION

[0001] This application is a divisional application of U.S. patent application Ser. No. 10 / 319,645, filed Dec. 16, 2002 which claims priority under 35 USC § 119(e) to Provisional Patent Application Ser. No. 60 / 344,817 filed on Jan. 7, 2002.FIELD OF THE INVENTION

[0002] The present invention relates generally to the field of seed treatments. More specifically, the present invention relates to biological seed treatment by naturally occurring sulfur-oxidizing rhizobacteria to enhance canola performance in an environmentally friendly manner. BACKGROUND OF THE INVENTION

[0003] Recent advances in soil microbiology and biotechnology have resulted in renewed interest to the use of microbial inoculants in agriculture, forestry and environmental management. Among the microbial inoculants, bacteria from the plant's rhizosphere and rhizoplane (rhizobacteria), are receiving considerable attention with respect to plant growth promotion, Rhizobacteria influence plant growth via d...
